Super Mario 64 DS is a Nintendo DS exclusive game, created by Nintendo's Entertainment Analysis and Development studio, and released by the Japanese company itself for the handheld platform, on November 21, 2004, in North America, December 2, that same year, in Japan, on February 24, 2005, in Australia, and on March 11, 2005, in Europe, as a new and improved version of its classic Nintendo 64 game Super Mario 64.
The original title became an instant classic back in the 1990s, being the first 3D Mario game in the history of Nintendo's massive franchise, so the developer hasn't tried to implement that many changes to its core gameplay, but did improve on the visuals, by taking advantage of the more powerful DS, while adding new characters, like Yoshi or Wario, and new special areas to the game's virtual world.
HINTS
Easy lives
-Play a level with a 1-Up, such as Bomb-Omb Battlefield. Collect the 1-Up mushrooms, leave the level, then go back in and repeat. You can do this as many times as desired.
-Go up to the room with each character's door. There will be a stained-glass portrait of Princess Peach. Jump into the portrait on the right-hand side of the room to access a Secret Star room. Go down the slide in front of you and about halfway down, you will run into a 1-Up. Repeat this as many times as needed.
-You must have at least 8 Stars and Mario unlocked for this trick. Go to the area where you unlocked Mario (past the character selection, through the door that required eight Stars to unlock, in the portrait of Mario) as Mario. Go down the tree stump to fight Goomboss, then kick the back of his head to get the mushroom. Eat it and wait for him to turn. He will create three Goombas at a time. Because you are big, you will automatically kill them. Continue to stand there and you will start racking up lives (three at a time). You can get up to fifteen lives at a time by doing this. Once the mushroom wears off, kill yourself and jump back in, repeating the process.
